The man who was charged with stabbing Paul Pierce a decade ago was convicted Thursday in federal court for stabbing a Drug Enforcement Administration informant, according to a report in The Boston Globe.

Trevor A. Watson, 44, stabbed the informant 10 times outside a South End barbershop on Feb. 27, U.S. Attorney Carmen M. Ortiz said in a statement. The victim, who underwent emergency surgery to repair his colon and intestine, had provided information against Watson in a federal cocaine trafficking investigation.

Watson, of Dorchester, first was tried in October, but that trial ended with a hung jury. He is scheduled to be sentenced on March 10 and faces up to 30 years in prison. He also is due in court in January to face a charge of conspiracy to distribute cocaine. Watson previously has been convicted of robbery, armed robbery, assault and battery and possession of a Class B substance.

Watson was charged with attempted murder in 2000 for allegedly stabbing Pierce in his head, back and face at the Buzz, a now-defunct nightclub in Boston’s theater district. Watson only was convicted of assault and battery after multiple witnesses changed their testimony at his trial. He was sentenced to one year in prison for his role in the attack. Another man, William Ragland, received a sentence of 7-10 years in state prison for assault and battery with a dangerous weapon in the incident.
